Cableone did this back in the day, they called it Sega Channel. You plugged a box into the cartridge slot, hooked up the coax cable, and every month you had 50 random sega games itemized by category. It changed monthly and you downloaded the game into the box and played, once it was turned off, you lost everything. It was supposed to have space for 3 save games but mine never worked.
